Carbonylation of olefinically unsaturated compounds

ABSTRACT

Oxygenated organic compounds, e.g. esters, aldehydes, and amides, are prepared by reacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of a catalyst comprising cobalt or ruthenium carbonyl and a promoter ligand. The promoter ligand is selected from the group consisting of heterocyclic nitrogen compounds and phosphorus or sulfur oxides. These reactions are carried out under relatively mild conditions of temperature and pressure.

This is a division of application Ser. No. 973,069 filed Dec. 26, 1978, now abandoned.

BACKGROUND OF THE INVENTION

The present invention relates to a novel process for producing oxygenated organic compounds.

There are several known methods for producing oxygenated organic compounds. The acid catalyzed (H₂ SO₄,HBF₄, etc.) synthesis of carboxylic acids or esters by the reaction of an olefinic substrate with CO and water or alcohol has been known since 1931. (J. Falbe, "Carbon Monoxide in Organic Synthesis", Springer-Verlag, New York (1970)). Although this process was used on a commercial scale it does have serious limitations due to the reaction conditions and the isomeric composition of the products.

A more commercially important synthesis of carboxylic acid/esters is the direct carbonylation of olefinic substrates with CO and water/alcohol conducted in the presence of transition metals. In general, this carbonylation reaction, discovered by Repp in 1940 (I. Wender and P. Pino, "Organic Synthesis Via Metal Carbonyls", Volume 2, John Wiley, New York (1977)), involves the addition of carbon monoxide, carboxyl alkyl or amide group (Y--H where Y equals --OR or --NHR and R is an alkyl), and an olefin.

However, when an unsymmetrical olefin is used as the substrate at least two isomeric products are obtained. No general method has been developed for the control of the isomeric product composition.

The present invention overcomes some of these problems present in the prior art. For example, the inventive process results in higher conversions, higher yields and faster reaction rates than those disclosed in the prior art. Furthermore, the instant process allows one to obtain a high yield of a particular isomeric product composition. Thus, extremely high selectivities of particular oxygenated organic compounds can be obtained by the inventive process.

Finally, the prior art carbonylation reactions operate under extreme conditions of temperature and pressure. In general, temperatures in the range of 160° C. to 300° C. and pressures in the range of 1,500 to 5,000 psi are required. On the other hand, the present reaction may be carried out under relatively mild conditions of temperature and pressure. This further advantage can result in substantial cost savings in the production of oxygenated organic compounds.

SUMMARY OF THE INVENTION

It has now been discovered that oxygenated organic compounds can be produced by contacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of a catalyst comprising cobalt and/or ruthenium carbonyl and a promoter ligand selected from the group consisting of heterocyclic nitrogen compounds and phosphorus or sulfur oxides.

In particular, the inventive process results in high yields of oxygenated organic compounds when operating at much lower temperatures and pressures than disclosed in the prior art. In addition, the product distribution can be varied significantly by changing the CO/H₂ ratio, pressure, ligand, solvent, reaction time and other process variables.

Thus, the present invention provides a novel catalyst comprising a promoter ligand and at least one of cobalt and ruthenium carbonyl. Furthermore, the instant invention provides a novel process for the production of an oxygenated organic compound comprising contacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of the above catalyst. Finally, the present invention provides a novel process for the production of an oxygenated organic compound comprising contacting an olefinically unsaturated compound containing an alcohol moiety with carbon monoxide in the presence of the above catalyst.

Specifically, the carbonylation reaction of acrylonitrile, carbon monoxide, hydrogen gas, and methanol to yield methyl-β-cyanopropionate proceeds smoothly using a catalyst comprising cobalt carbonyl and a heterocyclic nitrogen oxide promoter ligand.

DETAILED DESCRIPTION

According to the present invention, improved yields and selectivities of oxygenated organic compounds are obtained by contacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom over a catalyst comprising cobalt and/or ruthenium carbonyl and a promoter ligand selected from the group consisting of heterocyclic nitrogen compounds and phosphorous or sulfur oxides. The overall reaction taking place in this process is represented by the following equation: ##STR1## R₁, R₂ and Y are defined below.

Reactants

Olefinically unsaturated compounds which can be employed as reactants in the inventive process have the following structure:

    R.sub.11 CH═CHR.sub.12

wherein R₁₁ and R₁₂ are each independently selected from:

(1) hydrogen (either R₁₁ or R₁₂ but not both);

(2) C₁₋₃₀ alkyl;

(3) --(CH₂)_(p) --CN, wherein p is 0-3; and

(4) --(CH₂)_(q) --OR₁₃, wherein q is 1-30 and R₁₃ is hydrogen or methyl.

Preferably, the olefinically unsaturated compounds comprise compounds wherein R₁₁ and R₁₂ are each independently selected from:

(1) hydrogen (either R₁₁ or R₁₂ but not both);

(2) C₁₋₁₀ alkyl;

(3) --(CH₂)_(p) --CN, wherein p is 0-2; and

(4) --(CH₂)_(q) --OH, wherein q is 1-10.

Most preferably, the olefinically unsaturated compounds comprise compounds wherein R₁ and R₂ are each independently selected from hydrogen (either R₁ or R₂ but not both), methyl and --(CH₂)_(p) --CN, wherein p is 0-1.

The second component in the inventive reaction system is a compound containing a replaceable hydrogen atom. This compound can be represented by the following formula:

    H--Y

wherein Y is selected from the group consisting of:

(1) OR₁₄ wherein R₁₄ is a C₁₋₃₀ alkyl;

(2) ##STR2## wherein R₁₅ and R₁₆ are each independently selected from C₁₋₁₀ alkyls; and

(3) H.

Preferably Y is selected from the group consisting of:

(1) OR₁₄ wherein R₁₄ is a C₁₋₁₀ alkyl;

(2) ##STR3## wherein R₁₅ and R₁₆ are each independently selected from C₁₋₄ alkyls; and

(3) H.

More preferably Y is selected from the group consisting of:

(1) OR₁₄ wherein R₁₄ is a C₁₋₄ alkyl; and

(2) H.

The second component is most preferably either methanol or hydrogen.

In the embodiment of the invention in which H-Y is an alcohol or amine, it is preferred to add hydrogen gas to the reaction system. Preferably the amount of hydrogen gas so added comprises less than 10% by volume of the total amount of the hydrogen gas and carbon monoxide gas in the reaction system. More preferably the hydrogen gas comprises 0.5% to 7.5% by volume of the hydrogen and carbon monoxide gas. The addition of hydrogen gas can increase both the yield and selectivity to desired products in this mode of the invention.

When H₂ is the compound containing a replaceable hydrogen atom then the reaction system will preferably contain 10% to 60% by volume hydrogen gas based on the total volume of the carbon monoxide and hydrogen gas. More preferably the reaction system will contain about 50% hydrogen gas.

One way to supply carbon monoxide and hydrogen gas into the reaction system is in the form of synthesis gas. The amount of hydrogen in the synthesis gas can be easily adjusted prior to insertion into the reactor.

The amount of carbon monoxide in the reaction system is not critical. Preferably the carbon monoxide is present in at least stoichiometric amounts and most preferably the carbon monoxide is present in amounts greatly in excess of stoichiometric amounts. If desired, a carrier gas which is inert to the reactants, products and catalyst can be included in the reaction system.

The molar ratio of the compound containing a replaceable hydrogen atom to the olefinically unsaturated compound can be 0.5-100:1 with a ratio of 1-10:1 being preferred. This ratio does not include the hydrogen gas which may be added to the reaction system when H-Y is an alcohol or amine.

In the embodiment of the invention in which the olefin reactant is an alcohol (i.e. wherein R₁ or R₂ is --(CH₂)_(q) --OH), it has been found that the terminal hydrogen atom on the alcohol group will itself serve as a replaceable hydrogen atom. As a result, the alcohol moeity of the olefin will react with the olefinic double bond of the olefin thereby producing a lactone. In this reaction system no H-Y component need be included since the olefin itself acts both as the olefin and the H-Y component. The reaction in this particular system is shown by the following equation: ##EQU1## wherein at least one of R₁ and R₂ is an alcohol.

Process Conditions

Generally, in carrying out the inventive process, the olefinically unsaturated compound, carbon monoxide, and the compound containing a replaceable hydrogen atom are contacted with one another in the liquid phase in the presence of the catalyst described below. The inventive reaction can be accomplished in the batch mode or continuously.

The reaction temperature is normally maintained between 50° C. to 150° C. and most preferably at about 100° C. The reaction pressure is normally maintained at 100 to 2500 psi, preferably at 700 to 1000 psi. When the reaction is carried out in a batch mode, the reactants and catalysts are contacted with one another for a period of ten minutes through six hours, and preferably one half hour to four hours. A reaction time of less than ten minutes or more than six hours can be used if desired although better results will be obtained if the reaction time is maintained within this range. When the process is carried out on a continuous basis, the reaction catalyst time is normally 10 seconds to 10 minutes, preferably 100 seconds to 5 minutes.

Both the rate of reaction and product distribution can be varied significantly by changing the process parameters. For example, normally an increase in pressure increases the rate of reaction. However, at very high pressures the reaction rate may decrease due to catalyst decomposition. Furthermore, the selectivity to a particular product may be affected by pressure changes, e.g. in the carbonylation of acrylonitrile there is an increase in the selectivity to the n-cyanoester (3CE) as the pressure decreases.

A balance exists between temperature and pressure with respect to catalyst decomposition. Generally, as the temperature increases the rate of reaction increases. However, an anomolous effect may occur due to partial catalyst decomposition. Thus, the temperature and pressure must be carefully adjusted.

Similarly, residence time has a large effect on homogeneous processes. For example, in the process for the carbonylation of acrylonitrile, the selectivity to methyl-β-cyanopropionate is much higher at short reaction times. Applicants surmise that the reduction is selectivity as a function of reaction time is caused by the reduction of the ligand, e.g. 4-picoline-N-oxide is reduced to 4-picoline. In view of the above discussion, it is clear that a particular reaction rate and product distribution can be obtained by a careful adjustment of the process variables.

Catalysts

The catalyst employed in the inventive process can be generally described as one of two types. Both types comprise cobalt and/or ruthenium carbonyl and a promoter ligand in an organic solvent. The promoter ligand is either a heterocyclic nitrogen compound or a phosphorus or sulfur oxide.

The nitrogen heterocyclic promoter ligand has the following structure: ##STR4## wherein X is one of N and NO; and wherein R₁, R₂, R₃, R₄, and R₅ are each independently selected from the group consisting of:

(1) H;

(2) C₁₋₁₀ alkyls;

(3) (CH₂)_(q) OH wherein q is 0-10;

(4) ##STR5## wherein s is 0-10; and (5) O(CH₂)_(t) CH₃ wherein t is 0-10;

wherein R₁ and R₂ may comprise a five to eight membered carbocyclic fused ring optionally substituted with C₁₋₁₀ alkyls.

Preferably, X is NO, and R₁, R₂, R₃, R₄, and R₅ are selected from H, C₁₋₄ alkyls, CH₂ OH, OH, ##STR6## and OCH₃. Most preferably, R₁, R₂, R₃, R₄, and R₅ are selected from H, CH₃, and OCH₃.

The phosphorus or sulfur oxide promoter ligands have the following formulae: ##STR7## wherein R₆, R₇, R₈, R₉, and R₁₀ are each independently selected from:

(1) C₁₋₁₀ alkyls;

(2) polynuclear aryls containing up to 12 carbon atoms, optionally substituted with C₁₋₁₀ alkyls; and

(3) O(CH₂)_(t) CH₃, wherein t is 0-10; and

wherein n is 0 or 1.

Preferably, R₆, R₇, R₈, R₉, and R₁₀ are each independently selected from C₁₋₄ alkyls and most preferably R₆, R₇, R₈, R₉, and R₁₀ are CH₃.

The inventive catalyst can be prepared by mixing the cobalt and/or ruthenium carbonyl with at least one promoter ligand in a solvent. The cobalt and/or ruthenium carbonyl and the promoter ligand may be added simultaneously or separately to the solvent. The exact relationship in the solvent between the cobalt and/or ruthenium carbonyl and the promoter ligand is not known.

Any solvent in which the catalyst is soluble may be used in the present invention. Preferably, the solvent is an alcohol, aromatic, ester, nitrile and/or dinitrile. The solvent is most preferably an alcohol or ester. In fact, the alcohol can be both a compound containing a replaceable hydrogen atom described above and the solvent. The preferred catalyst concentration in the solvent is normally between 0.1% to 5% by weight.

The cobalt and/or ruthenium carbonyl can be added to the solvent in any form which cobalt and/or ruthenium carbonyl could be formed. For example, it is well known in the art that carbonyls can be formed from naphthalates, salts and nitrates and thus suitable naphthalates, salts and nitrates can be added to the solvent to form a carbonyl compound in situ. Preferably, the catalyst contains cobalt carbonyl.

In general, the promoter ligand to cobalt and/or ruthenium carbonyl molar ration is 0.1-50:1, preferably about 0.5-4, and most preferably about 2:1. This ratio will vary depending on the promoter ligand chosen. At high ligand to carbonyl ratios (i.e. 4:1) the rate of reaction substantially decreases even though selectivity to the desired product may be increased. Thus, in the carbonylation of acrylonitrile, at high ligand/carbonyl ratios the reaction rate decreases but the selectivity to methyl-β-cyanopropionate increases.

The catalyst of this invention is dissolved in the reaction medium as a homogeneous catalyst. These homogeneous catalysts are prepared by known techniques. Specific preparations of these catalysts are shown in the working examples of this specification. Broadly, however, the catalysts of this invention can be prepared by any of the techniques known in the art.

Recovery

The reaction product obtained upon completion of the reaction is normally in the form of a liquid and composed primarily of unreacted reactions, catalyst and oxygenated organic compounds. This reaction product can be subjected to suitable known separation techniques, i.e. solvent extraction and fractional distillation, to yield the desired end products.

A particularly good method for separating the catalyst from the products obtained in the present process is by the use of conjugate phase extraction. In this separation scheme, the reaction effluent is treated with a C₅ to C₈ hydrocarbon which is miscible with the reaction solvent but which is a very poor solvent for the catalyst. Examples of such hydrocarbons are pentane, hexane and octane. Enough of this hydrocarbon is added to the reactor effluent to separate almost all of the catalyst into one phase and a significant amount of products into the other phase. Generally, this is between 1 to 4 volumes of hydrocarbon per volume of reactor effluent.

It is desirable to exclude oxygen from this separation system so that catalyst decomposition will not occur. It is also desirable to minimize the amounts of unreacted substrates in the reactor effluent prior to treatment with the hydrocarbon. This can be accomplished by simple distillation or vacuum stripping. Finally, it is desirable to separate the products and reactants as quickly as possible to reduce the possibility of unwanted side reactions, e.g. methyl-β-cyanopropionate reacts with acrylonitrile to produce a dicyano ester.

The catalyst containing hydrocarbon phase can be diluted and recycled back to the reactor. The product phase is then subjected to known separation techniques such as distillation or extraction.

The oxygenated organic compounds produced by this process are useful as precursors to polymers. The esters are also useful in perfumes, flavorings and pharmaceuticals. The aldehydes are useful as plasticizers and as intermediates for alcohols.

SPECIFIC EMBODIMENTS

In order to more thoroughly illustrate the present invention, the following working examples are presented. In these examples, the following definitions are used: ##EQU2## The results have all been adjusted to a 100% carbon balance.

In general, the experimental method consists of placing a pre-weighed solution of olefinically unsaturated compound, promoter ligand, compound containing a replaceable hydrogen atom and solvent into a glasslined autoclave. Next, cobalt carbonyl, Co₂ (CO)₈, is added and the autoclave sealed.

The autoclave is flushed two times with synthesis gas and then charged with the synthesis gas to the desired pressure. The temperature is then increased and the reaction proceeds for 1 to 4 hours. Occasionally, samples are withdrawn during the course of the reaction through the vent tube and subjected to gas chromatography analysis. After the runs, the glasslined autoclave is brought to room temperature by cooling with cold water, depressurized and opened for product analysis.

EXAMPLE 101

In each of the above example, methanol was used as the compound containing a replaceable hydrogen atom. In the following examples, either t-butyl alcohol or n-amyl alcohol were used in place of methanol.

13.5 gms. of acrylonitrile, 0.88 gms. of 4-picoline-N-oxide and 100 mls. of t-butyl alcohol were placed into a glasslined autoclave. Next, 1.37 gms. of Co₂ (CO)₈ were added and the autoclave sealed.

The autoclave was charged with synthesis gas containing 5% H₂ to a pressure of 800 psi. The temperature was set at 97.5° C. and the reaction proceeded for 180 minutes. The glasslined autoclave was then brought to room temperature by cooling with cold water, depressurized and opened for product analysis. The product analysis is shown in Table II.

EXAMPLES 102 AND 103

These examples follow the same procedure outlined in Example 101 except that the solvent, alcohol and reaction time were varied. These variables and the product analysis are shown in Table II.

EXAMPLES 104

In each of the above examples the unsaturated olefin feed was acrylonitrile. In the following two examples, other olefins were fed to the inventive reaction system.

5.26 gms. of propylene, 0.88 gms. of 4-picoline-N-oxide, 8.15 gms. of methanol and 100 mls. of orthoxylene were placed into a glasslined autoclave. Next, 1.37 gms. of Co₂ (CO)₈ were added and the autoclave sealed.
